Struct TrueHeader 

pub struct TrueHeader {
    pub planes: Option<[(u32, u32); 3]>,
    pub seeds: [u16; 3],
    pub table: Vec<(u8, u8)>,
    pub plane_sizes: [u32; 3],
    pub data_offset: usize,
}

Parsed header of a TRUE-engine raw image section (after the 28-byte image header).

Fields

planes: Option<[(u32, u32); 3]>

Quattro plane sizes (columns, rows) (bottom, middle, top) when present.

seeds: [u16; 3]

table: Vec<(u8, u8)>

(code_size, code) pairs; the symbol of entry i is i (the diff bit length).

plane_sizes: [u32; 3]

data_offset: usize

Offset of the first plane’s data within the parsed slice.

Implementations

impl TrueHeader

pub fn parse(d: &[u8], quattro: bool) -> Result<Self>

Parse from the image payload (the bytes following the 28-byte SECi header).

pub fn table(&self) -> Result<TrueTable>

The decoding table for the planes.

pub fn code(&self) -> Result<PrefixCode>

The prefix code (symbol = diff bit length).

pub fn plane_ranges(&self, data_len: usize) -> Result<[(usize, usize); 3]>

Byte ranges (start, end) of each plane within data (relative to the data start). A plane’s stream may legally run into the following plane’s padding, so end is the end of all image data.

Trait Implementations

impl Clone for TrueHeader

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TrueHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
